The partially observable predator-prey environment consists of 8 predators and 8 prey in a \(10\times 10\)  grid world. The predator can only observe a \(5\times 5\)  sub-grid around it. A
successful catch is defined as that two adjacent agents perform catch operation simultaneously, which is rewarded with a global reward \(r=10\) . The miscoordination, i.e., only one
agent attempts to catch, is punished by a penalty \(p\le 0\) . It is proved that the stronger penalty causes failures in many non-communication algorithms [1]}, [2]}.
